    <p>
        If a signal is registered with a signal_set, and the signal occurs when
        there are no waiting handlers, then the signal notification is queued.
        The next async_wait operation on that signal_set will dequeue the notification.
        If multiple notifications are queued, subsequent async_wait operations
        dequeue them one at a time. Signal notifications are dequeued in order
        of ascending signal number.
    </p>

        If a signal number is removed from a signal_set (using the <code class="computeroutput"><span

            class="identifier">erase</span></code>
        member functions) then any queued notifications for that signal are discarded.

        POSIX allows signals to be blocked using functions such as <code class="computeroutput"><span
            class="identifier">sigprocmask</span><span class="special">()</span></code>
        and <code class="computeroutput"><span class="identifier">pthread_sigmask</span><span class="special">()</span></code>.
        For signals to be delivered, programs must ensure that any signals registered
        using signal_set objects are unblocked in at least one thread.
